NASHVILLE, Tenn. -- The town hall debate at Belmont University is a different format than the others because the questions come from the public.

On Tuesday before the debate, the 80 to 120 people selected randomly by the Gallup Organization will meet with moderator Tom Brokaw. Every participant is supposed to come with a question to ask the candidates.

Brokaw will talk with the participants about those questions and select which ones to use.

But you don't have to be a part of the town hall meeting to have a chance to ask Sen. Barack Obama or Sen. John McCain a question.

You can log on to mydebates.org to submit a question for the town hall meeting. Then it's up to Brokaw to choose what questions go to the candidates.

Both candidates will have two minutes to answer each question, followed by a five-minute discussion between the two candidates.
